Realistic 3D Reconstruction from Two Uncalibrated Views
نویسندگان
چکیده
An approach for 3D surface reconstruction from two uncalibrated views is proposed in this paper. The SUSAN corner detector is used for corners from points in edges, which are detected by Sobel edge operator. After corners matching between two images, the fundamental matrix is estimated to acquire 3D structure from matched corners by an improved weighted linear algorithm, which is based on the epipolar geometry and the absolute conic theory. The triangular textures are acquired by dividing 2D image. Then a realistic 3D surface model is built by mapping the triangular textures to the 3D structure surface. Experiments show that the reconstructed 3D surface models are satisfactory and photo-realistic.

Uncalibrated 1D projective camera and 3D affine reconstruction of lines
We describe a linear algorithm to recover 3D affine shape/motion from line correspondences over three views with uncalibrated affine cameras. The key idea is the introduction of a one-dimensional projective camera. This converts the 3D affine reconstruction of “lines” into 2D projective reconstruction of “points”. Using the full tensorial representation of three uncalibrated 1D views, we prove ...

متن کاملProjective Reconstruction of General 3D Planar Curves from Uncalibrated Cameras
In this paper, we propose a new 3D reconstruction method for general 3D planar curves based on curve correspondences on two views. By fitting the measured and transferred points using spline curves and minimizing the 2D Euclidean distance from measured and transferred points to fitted curves, we obtained an optimum homography which relates the curves across two views. Once two or more homograph...
متن کاملThe Precision of 3D Reconstruction from Uncalibrated Views
We consider reconstruction algorithms using points tracked over a sequence of (at least three) images, to estimate the positions of the cameras (motion parameters), the 3D coordinates (structure parameters), and the calibration matrix of the cameras (calibration parameters). Many algorithms have been reported in literature, and there is a need to know how well they may perform. We show how the ...
متن کاملA Comparison of Projective Reconstruction Methods for Pairs of Views
Recently, different approaches for uncalibrated stereo have been suggested which permit projective reconstruction from multiple views. These use weak calibration which is represented by the epipolar geometry, and so no knowledge of the intrinsic or extrinsic camera parameters is required. In this paper we consider projective reconstructions from pairs of views, and compare a number of the avail...
